<p>Apparatus for subdividing a stack into a number of piles of overlapping sheets has an elevator which can move a stack upwardly in stepwise fashion between a belt conveyor and a horizontally reciprocable carriage for a pusher and a blade-like horizontal separating element which extends beyond the pusher in a direction toward the conveyor. When a selected part of the stack extends above the level of the upper reach of the conveyor, the carriage is moved toward the conveyor so that the separating element penetrates between two sheets of the stack and the pusher thereupon transfers the pile above the separating element onto the conveyor. Two hold-down devices enter the gap which is formed in the stack as a result of penetration of the separating element to prevent the topmost sheet of the remaining portion of the stack from participating in the movement of the separating element toward the conveyor. The thickness of the rounded tip of the separating element is less than 0.9 millimeter.</p> |
